` ATTLNT JAMES FRANK PATTERSON, OF DUNMORE, WEST VIRGINIA.

APPLE-MILL.

SPECIFICATION forming part of Letters Patent No. 275,939, dated .April 17', 1883.

Application filed December 2T, 188i. (No model.)

l'o all whom it may concern Be it known that 1, J. FRANK PATTERSON, of Dunmore, in the county of Pocahontas and State of West Virginia, have invented a new and Improved Apple-Mill, of which the following is a full, clear, and exact description.

My invention consists of a contrivance of a crushing or grinding wheel, and boxes or ca-ses in which the 'wheel works, in which the essential feature consists of radially-shifting arms contrived with crushing-ledges in the boxes, which gradually converge on the face of the wheel, so as to successively reduce the apples to the required degree of ineness, the said arms receding as the spaces between the wheelface and the boxes diminish, together with a novel feeding apparatus, all being contrived to enable the entire mill to be constructed of wood for economy of materials and construction, and also to avoid the use of metals, which are injurious to the cider, as hereinafter more fully described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is partly a plan view and partly a horizontal section of my improved apple-mill.

Fig. 2 is a sectional elevation taken on line m x' of Fig. 1. Fig. 3 is a section on line y y' of Fig. 1, and Fig. 4 is a section of the feeding-hopper on line .c a of Fig. 2.

I make a skeleton grinding-wheel consisting of the face-rim a, arms b, shaft c, outer top and bottom rims, d, and inner top and bottom rims or disks, c, and mount said wheel so as to turn in a horizontal plane by fixing the shaft upright in suitable bearin gs in the crossbeams f of a strong frame, of which g represents the longitudinal beams, and h the end pieces or heads. The face-rim a has radial slots cut through it at suitable intervals, in which the radial shifting arms t' are fitted between the rims d, 'said arms also having bearings in the rims or disks e, as indicated by the dotted lines in Fig. 1. The slots through rim a are made to widen from about an inch from the face to the interior ofthe rim for clearance of any pomace that may crowd in, to avoid friction as much as possible. (See dotted lines, Fig. 1.) The rims d are an inch, or thereabout, smallerin diameter than the rim c is, to form a rabbet, in

which the inner edges of the coversj of the griliding-boxes lo t to makejoints to prevent the escape of pomace thereat and steady the wheel. The grinding boxes or cases have notched faces forming ledges l, and converging on the face c of the wheel. Two such boxes are used with one wheel, said boxes being opposite each other, in order that the lateral thrusts will be balanced and side pressure on the shaft will be avoided. The parts m of said boxes having the ledges are to be constructed so as to take the wear on the ends of the grains of the wood for greater power to sustain the wear.

The apples are to be fed into the grindingboxes through passages4 o from hoppers n, `mounted on the upper covers,j, where they are pushed against the ledges Zand crushed by the arms z', which are thrust out by cams p and pins q to the plain and circular parts s of the faces of the boxes' in advance of the converging ledges, preparatory to crushing the apples on said ledges. The said arms are pressed back by said ledges, so as to clear them. The plain and circular parts s of the grindingboxes are longer than the spaces between the arms, in order that said parts will always be closed in advance of where the apples fall in the boxes to prevent any from escaping. The gri ndin g-boxes are backed against the heads h. by removable piecest at one end and adjustingscrewsn at the other end, by which they may be shifted with respect to the face a of the grinding- Wheel, as may be required from time to time to obtain the desired degree of lineness ofpomace. In order that the hoppers may be shaken'properly for feeding theiapples, they are connected with the plates of frame and end pieces or heads by hooks w and suitable staples, and have a projecting stud, x, which drops in and rises out of the notches y in the upper rim, d, causing the hopper to rise and fall, so as to jolt the apples and prevent them from clogging. The wheel is to be turned by power applied to a sweep, e, attached to the upper end of the shaft. The face of the wheel is to be cleared of pomace adhering to it by Scrapers c', pressed on its face by springs b', said scrapers being arranged obliquely across the face a, and slightly beveled at the end rst encountered by the arms i to allow them to pass in case they may project a little and crowd 'them IOO back. rIhe arms t' serve as feeders to pass or feed along the apples in the boxes s to the crushing-ledges.'

It will be seen that the machine is simple in contrivance and very cheap ot' construction, at the same time being well calculated for efficiency and durability.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. The combination, with the grinding-box k, having the ledges l and the plain circular rim s, ot' a revolving wheel having sliding feeding-'arms t', and means for thrusting out the said arm, substantially as herein shown and described.

2. The combination, in an apple-mill, of slotted wheel-rim a., arms b, upper and lower rims, d e, and shaft c, said shaft being mounted in a suitable frame and arranged with a grinding box or boxes, substantially as described.

3. `The combination, with the grinding-box lr, having the ledges l and the plain circular rim s, of a revolving wheel having sliding feeding-arms t', provided with pins qand the cams p, substantially as herein shown and described.

4. The combination, with the grinding-box 7c, having ledges l and plain rim s, of arevolving Wheelhavingradially-slidingfeeding-arms, and the coversj, adapted to fit between the rims a d of the Wheel, substantially as herein shown and described.

5. The combination, with the frame g h, and a revolving Wheel having radially-slidin g feeding-arms, the grinding-box 7c, the removable piece t, placedbetween the back of the box and the head h ot' the frame, and the adjustingscrew u, passing through the said head and pressing against the feeding-box, substantially as herein shown and described.

6. The combination of hopper u, grindingbox, and grinding-arms, said hopper being mounted on said box by suitable means for vertical action, and having stud w, arranged with respect to notches y on the outer top rim, d, substantially as described. 4

7. The combination of scrapers a with the wheel-rim a and arms i, said Scrapers being arranged diagonally across the face of said wheel-rim, substantially as described.

S. The combination, in an apple-mill, of rotary and radially-reciprocating arms i, mounted in a suitable carrying-wheel, and two grinding-boxes having ledges l, converging on the face of the wheel, said boxes being arranged on opposite sides of the wheel, substantially as described.
